Mental Disorders Medications
MEDICATIONS FOR MENTAL ILLNESS
This page describes medications by their
generic (chemical) names and in italics by their trade names
(brand names used by pharmaceutical companies). They are
divided into four large categories—antipsychotic, antimanic,
antidepressant, and antianxiety medications. Medications that
specifically affect children, the elderly, and women during
the reproductive years are also discussed.
Lists at
the end of the page give the generic name and the trade
name of the most commonly prescribed medications. A separate
chart shows the trade and generic names of medications
commonly prescribed for children and
adolescents.
Treatment
evaluation studies have established the effectiveness of the
medications described here, but much remains to be learned
about them. The National Institute of Mental Health, other
Federal agencies, and private research groups are sponsoring
studies of these medications. Scientists are hoping to improve
their understanding of how and why these medications work, how
to control or eliminate unwanted side effects, and how to make
the medications more effective.
ANTIPSYCHOTIC MEDICATIONS
A person
who is psychotic is out of touch with reality. People with
psychosis may hear "voices" or have strange and illogical
ideas (for example, thinking that others can hear their
thoughts, or are trying to harm them, or that they are the
President of the United States or some other famous person).
They may get excited or angry for no apparent reason, or spend
a lot of time by themselves, or in bed, sleeping during the
day and staying awake at night. The person may neglect
appearance, not bathing or changing clothes, and may be hard
to talk to—barely talking or saying things that make no sense.
They often are initially unaware that their condition is an
illness.
These kinds
of behaviors are symptoms of a psychotic illness such as
schizophrenia. Antipsychotic medications act against these
symptoms. These medications cannot "cure" the illness, but
they can take away many of the symptoms or make them milder.
In some cases, they can shorten the course of an episode of
the illness as well.
There are a
number of antipsychotic (neuroleptic) medications available.
These medications affect neurotransmitters that allow
communication between nerve cells. One such neurotransmitter,
dopamine, is thought to be relevant to schizophrenia symptoms.
All these medications have been shown to be effective for
schizophrenia. The main differences are in the potency—that
is, the dosage (amount) prescribed to produce therapeutic
effects—and the side effects. Some people might think that the
higher the dose of medication prescribed, the more serious the
illness; but this is not always true.
The first
antipsychotic medications were introduced in the 1950s.
Antipsychotic medications have helped many patients with
psychosis lead a more normal and fulfilling life by
alleviating such symptoms as hallucinations, both visual and
auditory, and paranoid thoughts. However, the early
antipsychotic medications often have unpleasant side effects,
such as muscle stiffness, tremor, and abnormal movements,
leading researchers to continue their search for better
drugs.
The 1990s
saw the development of several new drugs for schizophrenia,
called "atypical antipsychotics." Because they have fewer side
effects than the older drugs, today they are often used as a
first-line treatment. The first atypical antipsychotic,
clozapine (Clozaril), was introduced in the United
States in 1990. In clinical trials, this medication was found
to be more effective than conventional or "typical"
antipsychotic medications in individuals with
treatment-resistant schizophrenia (schizophrenia that has not
responded to other drugs), and the risk of tardive dyskinesia
(a movement disorder) was lower. However, because of the
potential side effect of a serious blood
disorder—agranulocytosis (loss of the white blood cells that
fight infection)—patients who are on clozapine must have a
blood test every 1 or 2 weeks. The inconvenience and cost of
blood tests and the medication itself have made maintenance on
clozapine difficult for many people. Clozapine, however,
continues to be the drug of choice for treatment-resistant
schizophrenia patients.
Several
other atypical antipsychotics have been developed since
clozapine was introduced. The first was risperidone
(Risperdal), followed by olanzapine (Zyprexa),
quetiapine (Seroquel), and ziprasidone (Geodon).
Each has a unique side effect profile, but in general, these
medications are better tolerated than the earlier
drugs.
All these
medications have their place in the treatment of
schizophrenia, and doctors will choose among them. They will
consider the person's symptoms, age, weight, and personal and
family medication history.
Dosages and side effects. Some drugs are
very potent and the doctor may prescribe a low dose. Other
drugs are not as potent and a higher dose may be
prescribed.
Unlike some
prescription drugs, which must be taken several times during
the day, some antipsychotic medications can be taken just once
a day. In order to reduce daytime side effects such as
sleepiness, some medications can be taken at bedtime. Some
antipsychotic medications are available in "depot" forms that
can be injected once or twice a month.
Most side
effects of antipsychotic medications are mild. Many common
ones lessen or disappear after the first few weeks of
treatment. These include drowsiness, rapid heartbeat, and
dizziness when changing position.
Some people
gain weight while taking medications and need to pay extra
attention to diet and exercise to control their weight. Other
side effects may include a decrease in sexual ability or
interest, problems with menstrual periods, sunburn, or skin
rashes. If a side effect occurs, the doctor should be told. He
or she may prescribe a different medication, change the dosage
or schedule, or prescribe an additional medication to control
the side effects.
Just as
people vary in their responses to antipsychotic medications,
they also vary in how quickly they improve. Some symptoms may
diminish in days; others take weeks or months. Many people see
substantial improvement by the sixth week of treatment. If
there is no improvement, the doctor may try a different type
of medication. The doctor cannot tell beforehand which
medication will work for a person. Sometimes a person must try
several medications before finding one that
works.
If a person
is feeling better or even completely well, the medication
should not be stopped without talking to the doctor. It may be
necessary to stay on the medication to continue feeling well.
If, after consultation with the doctor, the decision is made
to discontinue the medication, it is important to continue to
see the doctor while tapering off medication. Many people with
bipolar disorder, for instance, require antipsychotic
medication only for a limited time during a manic episode
until mood-stabilizing medication takes effect. On the other
hand, some people may need to take antipsychotic medication
for an extended period of time. These people usually have
chronic (long-term, continuous) schizophrenic disorders, or
have a history of repeated schizophrenic episodes, and are
likely to become ill again. Also, in some cases a person who
has experienced one or two severe episodes may need medication
indefinitely. In these cases, medication may be continued in
as low a dosage as possible to maintain control of symptoms.
This approach, called maintenance treatment, prevents relapse
in many people and removes or reduces symptoms for
others.
Multiple medications. Antipsychotic
medications can produce unwanted effects when taken with other
medications. Therefore, the doctor should be told about all
medicines being taken, including over-the-counter medications
and vitamin, mineral, and herbal supplements, and the extent
of alcohol use. Some antipsychotic medications interfere with
antihypertensive medications (taken for high blood pressure),
anticonvulsants (taken for epilepsy), and medications used for
Parkinson's disease. Other antipsychotics add to the effect of
alcohol and other central nervous system depressants such as
antihistamines, antidepressants, barbiturates, some sleeping
and pain medications, and
narcotics.
Other effects. Long-term treatment of
schizophrenia with one of the older, or "conventional,"
antipsychotics may cause a person to develop tardive
dyskinesia (TD). Tardive dyskinesia is a condition
characterized by involuntary movements, most often around the
mouth. It may range from mild to severe. In some people, it
cannot be reversed, while others recover partially or
completely. Tardive dyskinesia is sometimes seen in people
with schizophrenia who have never been treated with an
antipsychotic medication; this is called "spontaneous
dyskinesia." However, it is most often seen after long-term
treatment with older antipsychotic medications. The risk has
been reduced with the newer "atypical" medications. There is a
higher incidence in women, and the risk rises with age. The
possible risks of long-term treatment with an antipsychotic
medication must be weighed against the benefits in each case.
The risk for TD is 5 percent per year with older medications;
it is less with the newer
medications.
ANTIMANIC
MEDICATIONS
Bipolar
disorder is characterized by cycling mood changes: severe
highs (mania) and lows (depression). Episodes may be
predominantly manic or depressive, with normal mood between
episodes. Mood swings may follow each other very closely,
within days (rapid cycling), or may be separated by months to
years. The "highs" and "lows" may vary in intensity and
severity and can co-exist in "mixed"
episodes.
When people
are in a manic "high," they may be overactive, overly
talkative, have a great deal of energy, and have much less
need for sleep than normal. They may switch quickly from one
topic to another, as if they cannot get their thoughts out
fast enough. Their attention span is often short, and they can
be easily distracted. Sometimes people who are "high" are
irritable or angry and have false or inflated ideas about
their position or importance in the world. They may be very
elated, and full of grand schemes that might range from
business deals to romantic sprees. Often, they show poor
judgment in these ventures. Mania, untreated, may worsen to a
psychotic state.
In a
depressive cycle the person may have a "low" mood with
difficulty concentrating; lack of energy, with slowed thinking
and movements; changes in eating and sleeping patterns
(usually increases of both in bipolar depression); feelings of
hopelessness, helplessness, sadness, worthlessness, guilt;
and, sometimes, thoughts of suicide.
Lithium. The medication used most often
to treat bipolar disorder is lithium. Lithium evens out mood
swings in both directions—from mania to depression, and
depression to mania—so it is used not just for manic attacks
or flare-ups of the illness but also as an ongoing maintenance
treatment for bipolar
disorder.
Although
lithium will reduce severe manic symptoms in about 5 to 14
days, it may be weeks to several months before the condition
is fully controlled. Antipsychotic medications are sometimes
used in the first several days of treatment to control manic
symptoms until the lithium begins to take effect.
Antidepressants may also be added to lithium during the
depressive phase of bipolar disorder. If given in the absence
of lithium or another mood stabilizer, antidepressants may
provoke a switch into mania in people with bipolar
disorder.
A person
may have one episode of bipolar disorder and never have
another, or be free of illness for several years. But for
those who have more than one manic episode, doctors usually
give serious consideration to maintenance (continuing)
treatment with lithium.
Some people
respond well to maintenance treatment and have no further
episodes. Others may have moderate mood swings that lessen as
treatment continues, or have less frequent or less severe
episodes. Unfortunately, some people with bipolar disorder may
not be helped at all by lithium. Response to treatment with
lithium varies, and it cannot be determined beforehand who
will or will not respond to treatment.
Regular
blood tests are an important part of treatment with lithium.
If too little is taken, lithium will not be effective. If too
much is taken, a variety of side effects may occur. The range
between an effective dose and a toxic one is small. Blood
lithium levels are checked at the beginning of treatment to
determine the best lithium dosage. Once a person is stable and
on a maintenance dosage, the lithium level should be checked
every few months. How much lithium people need to take may
vary over time, depending on how ill they are, their body
chemistry, and their physical condition.
Side effects of lithium. When people
first take lithium, they may experience side effects such as
drowsiness, weakness, nausea, fatigue, hand tremor, or
increased thirst and urination. Some may disappear or decrease
quickly, although hand tremor may persist. Weight gain may
also occur. Dieting will help, but crash diets should be
avoided because they may raise or lower the lithium level.
Drinking low-calorie or no-calorie beverages, especially
water, will help keep weight down. Kidney changes—increased
urination and, in children, enuresis (bed wetting)—may develop
during treatment. These changes are generally manageable and
are reduced by lowering the dosage. Because lithium may cause
the thyroid gland to become underactive (hypothyroidism) or
sometimes enlarged (goiter), thyroid function monitoring is a
part of the therapy. To restore normal thyroid function,
thyroid hormone may be given along with
lithium.
Because of
possible complications, doctors either may not recommend
lithium or may prescribe it with caution when a person has
thyroid, kidney, or heart disorders, epilepsy, or brain
damage. Women of childbearing age should be aware that lithium
increases the risk of congenital malformations in babies.
Special caution should be taken during the first 3 months of
pregnancy.
Anything
that lowers the level of sodium in the body—reduced intake of
table salt, a switch to a low-salt diet, heavy sweating from
an unusual amount of exercise or a very hot climate, fever,
vomiting, or diarrhea—may cause a lithium buildup and lead to
toxicity. It is important to be aware of conditions that lower
sodium or cause dehydration and to tell the doctor if any of
these conditions are present so the dose can be
changed.
Lithium, when combined with certain
other medications, can have unwanted effects. Some
diuretics—substances that remove water from the body—increase
the level of lithium and can cause toxicity. Other diuretics,
like coffee and tea, can lower the level of lithium. Signs of
lithium toxicity may include nausea, vomiting, drowsiness,
mental dullness, slurred speech, blurred vision, confusion,
dizziness, muscle twitching, irregular heartbeat, and,
ultimately, seizures. A lithium overdose can be
life-threatening. People who are taking lithium should tell
every doctor who is treating them, including dentists, about
all medications they are
taking.
With
regular monitoring, lithium is a safe and effective drug that
enables many people, who otherwise would suffer from
incapacitating mood swings, to lead normal
lives.
Anticonvulsants. Some people with
symptoms of mania who do not benefit from or would prefer to
avoid lithium have been found to respond to anticonvulsant
medications commonly prescribed to treat
seizures.
The
anticonvulsant valproic acid (Depakote, divalproex
sodium) is the main alternative therapy for bipolar
disorder. It is as effective in non-rapid-cycling bipolar
disorder as lithium and appears to be superior to lithium in
rapid-cycling bipolar disorder. Although valproic
acid can cause gastrointestinal side effects, the incidence is
low. Other adverse effects occasionally reported are headache,
double vision, dizziness, anxiety, or confusion. Because in
some cases valproic acid has caused liver dysfunction, liver
function tests should be performed before therapy and at
frequent intervals thereafter, particularly during the first 6
months of therapy.
Other
anticonvulsants used for bipolar disorder include
carbamazepine (Tegretol), lamotrigine
(Lamictal), gabapentin (Neurontin), and
topiramate (Topamax). The evidence for anticonvulsant
effectiveness is stronger for acute mania than for long-term
maintenance of bipolar disorder. Some studies suggest
particular efficacy of lamotrigine in bipolar depression. At
present, the lack of formal FDA approval of anticonvulsants
other than valproic acid for bipolar disorder may limit
insurance coverage for these medications.
Most people
who have bipolar disorder take more than one medication. Along
with the mood stabilizer—lithium and/or an anticonvulsant—they
may take a medication for accompanying agitation, anxiety,
insomnia, or depression. It is important to continue taking
the mood stabilizer when taking an antidepressant because
research has shown that treatment with an antidepressant alone
increases the risk that the patient will switch to mania or
hypomania, or develop rapid cycling. Sometimes,
when a bipolar patient is not responsive to other medications,
an atypical antipsychotic medication is prescribed. Finding
the best possible medication, or combination of medications,
is of utmost importance to the patient and requires close
monitoring by a doctor and strict adherence to the recommended
treatment regimen.
ANTIDEPRESSANT
MEDICATIONS
Major
depression, the kind of depression that will most likely
benefit from treatment with medications, is more than just
"the blues." It is a condition that lasts 2 weeks or more, and
interferes with a person's ability to carry on daily tasks and
enjoy activities that previously brought pleasure. Depression
is associated with abnormal functioning of the brain. An
interaction between genetic tendency and life history appears
to determine a person's chance of becoming depressed. Episodes
of depression may be triggered by stress, difficult life
events, side effects of medications, or medication/substance
withdrawal, or even viral infections that can affect the
brain.
Depressed
people will seem sad, or "down," or may be unable to enjoy
their normal activities. They may have no appetite and lose
weight (although some people eat more and gain weight when
depressed). They may sleep too much or too little, have
difficulty going to sleep, sleep restlessly, or awaken very
early in the morning. They may speak of feeling guilty,
worthless, or hopeless; they may lack energy or be jumpy and
agitated. They may think about killing themselves and may even
make a suicide attempt. Some depressed people have delusions
(false, fixed ideas) about poverty, sickness, or sinfulness
that are related to their depression. Often feelings of
depression are worse at a particular time of day, for
instance, every morning or every evening.
Not
everyone who is depressed has all these symptoms, but everyone
who is depressed has at least some of them, co-existing, on
most days. Depression can range in intensity from mild to
severe. Depression can co-occur with other medical disorders
such as cancer, heart disease, stroke, Parkinson's disease,
Alzheimer's disease, and diabetes. In such cases, the
depression is often overlooked and is not treated. If the
depression is recognized and treated, a person's quality of
life can be greatly improved.
Antidepressants are used most often for serious
depressions, but they can also be helpful for some milder
depressions. Antidepressants are not "uppers" or stimulants,
but rather take away or reduce the symptoms of depression and
help depressed people feel the way they did before they became
depressed.
The doctor
chooses an antidepressant based on the individual's symptoms.
Some people notice improvement in the first couple of weeks;
but usually the medication must be taken regularly for at
least 6 weeks and, in some cases, as many as 8 weeks before
the full therapeutic effect occurs. If there is little or no
change in symptoms after 6 or 8 weeks, the doctor may
prescribe a different medication or add a second medication
such as lithium, to augment the action of the original
antidepressant. Because there is no way of knowing beforehand
which medication will be effective, the doctor may have to
prescribe first one and then another. To give a medication
time to be effective and to prevent a relapse of the
depression once the patient is responding to an
antidepressant, the medication should be continued for 6 to 12
months, or in some cases longer, carefully following the
doctor's instructions. When a patient and the doctor feel that
medication can be discontinued, withdrawal should be discussed
as to how best to taper off the medication gradually.
Never discontinue medication without talking to the doctor
about it. For those who have had several bouts of
depression, long-term treatment with medication is the most
effective means of preventing more
episodes.
Dosage of
antidepressants varies, depending on the type of drug and the
person's body chemistry, age, and, sometimes, body weight.
Traditionally, antidepressant dosages are started low and
raised gradually over time until the desired effect is reached
without the appearance of troublesome side effects. Newer
antidepressants may be started at or near therapeutic
doses.
Early antidepressants. From the 1960s
through the 1980s, tricyclic antidepressants (named for their
chemical structure) were the first line of treatment for major
depression. Most of these medications affected two chemical
neurotransmitters, norepinephrine and serotonin. Though the
tricyclics are as effective in treating depression as the
newer antidepressants, their side effects are usually more
unpleasant; thus, today tricyclics such as imipramine,
amitriptyline, nortriptyline, and desipramine are used as a
second- or third-line treatment. Other antidepressants
introduced during this period were monoamine oxidase
inhibitors (MAOIs). MAOIs are effective for some people with
major depression who do not respond to other antidepressants.
They are also effective for the treatment of panic disorder
and bipolar depression. MAOIs approved for the treatment of
depression are phenelzine (Nardil), tranylcypromine (Parnate),
and isocarboxazid (Marplan). Because substances in certain
foods, beverages, and medications can cause dangerous
interactions when combined with MAOIs, people on these agents
must adhere to dietary restrictions. This has deterred many
clinicians and patients from using these effective
medications, which are in fact quite safe when used as
directed.
The past
decade has seen the introduction of many new antidepressants
that work as well as the older ones but have fewer side
effects. Some of these medications primarily affect one
neurotransmitter, serotonin, and are called selective
serotonin reuptake inhibitors (SSRIs). These include
fluoxetine (Prozac), sertraline (Zoloft),
fluvoxamine (Luvox), paroxetine (Paxil), and
citalopram (Celexa).
The late
1990s ushered in new medications that, like the tricyclics,
affect both norepinephrine and serotonin but have fewer side
effects. These new medications include venlafaxine
(Effexor) and nefazadone
(Serzone).
Cases of
life-threatening hepatic failure have been reported in
patients treated with nefazodone (Serzone). Patients should
call the doctor if the following symptoms of liver dysfunction
occur—yellowing of the skin or white of eyes, unusually dark
urine, loss of appetite that lasts for several days, nausea,
or abdominal pain.
Other newer
medications chemically unrelated to the other antidepressants
are the sedating mirtazepine (Remeron) and the more
activating bupropion (Wellbutrin). Wellbutrin has not
been associated with weight gain or sexual dysfunction but is
not used for people with, or at risk for, a seizure
disorder.
Each
antidepressant differs in its side effects and in its
effectiveness in treating an individual person, but the
majority of people with depression can be treated effectively
by one of these antidepressants.
Side effects of antidepressant
medications. Antidepressants may cause mild, and often
temporary, side effects (sometimes referred to as adverse
effects) in some people. Typically, these are not serious.
However, any reactions or side effects that are unusual,
annoying, or that interfere with functioning should be
reported to the doctor immediately. The most common side
effects of tricyclic antidepressants, and ways to deal with
them, are as follows:
- Dry mouth—it is helpful to
drink sips of water; chew sugarless gum; brush teeth daily.
- Constipation—bran cereals,
prunes, fruit, and vegetables should be in the diet.
- Bladder problems—emptying the
bladder completely may be difficult, and the urine stream
may not be as strong as usual. Older men with enlarged
prostate conditions may be at particular risk for this
problem. The doctor should be notified if there is any pain.
- Sexual problems—sexual
functioning may be impaired; if this is worrisome, it should
be discussed with the doctor.
- Blurred vision—this is usually
temporary and will not necessitate new glasses. Glaucoma
patients should report any change in vision to the doctor.
- Dizziness—rising from the bed
or chair slowly is helpful.
- Drowsiness as a daytime
problem—this usually passes soon. A person who feels
drowsy or sedated should not drive or operate heavy
equipment. The more sedating antidepressants are generally
taken at bedtime to help sleep and to minimize daytime
drowsiness.
- Increased heart rate—pulse rate
is often elevated. Older patients should have an
electrocardiogram (EKG) before beginning tricyclic
treatment.
The newer
antidepressants, including SSRIs, have different types of side
effects, as follows:
- Sexual problems—fairly common,
but reversible, in both men and women. The doctor should be
consulted if the problem is persistent or worrisome.
- Headache—this will usually go
away after a short time.
- Nausea—may occur after a dose,
but it will disappear quickly.
- Nervousness and insomnia (trouble
falling asleep or waking often during the night)—these
may occur during the first few weeks; dosage reductions or
time will usually resolve them.
- Agitation (feeling jittery)—if
this happens for the first time after the drug is taken and
is more than temporary, the doctor should be notified.
- Any of
these side effects may be amplified when an SSRI is combined
with other medications that affect serotonin. In the most
extreme cases, such a combination of medications (e.g., an
SSRI and an MAOI) may result in a potentially serious or
even fatal "serotonin syndrome," characterized by fever,
confusion, muscle rigidity, and cardiac, liver, or kidney
problems.
The small
number of people for whom MAOIs are the best treatment need to
avoid taking decongestants and consuming certain foods that
contain high levels of tyramine, such as many cheeses, wines,
and pickles. The interaction of tyramine with MAOIs can bring
on a sharp increase in blood pressure that can lead to a
stroke. The doctor should furnish a complete list of
prohibited foods that the individual should carry at all
times. Other forms of antidepressants require no food
restrictions. MAOIs also should not be combined with other
antidepressants, especially SSRIs, due to the risk of
serotonin syndrome.
Medications of any
kind—prescribed, over-the-counter, or herbal
supplements—should never be mixed without consulting the
doctor; nor should medications ever be borrowed from another
person. Other health professionals who may prescribe a
drug—such as a dentist or other medical specialist—should be
told that the person is taking a specific antidepressant and
the dosage. Some drugs, although safe when taken alone, can
cause severe and dangerous side effects if taken with other
drugs. Alcohol (wine, beer, and hard liquor) or street drugs,
may reduce the effectiveness of antidepressants and their use
should be minimized or, preferably, avoided by anyone taking
antidepressants. Some people who have not had a problem with
alcohol use may be permitted by their doctor to use a modest
amount of alcohol while taking one of the newer
antidepressants. The potency of alcohol may be increased by
medications since both are metabolized by the liver; one drink
may feel like two.
Although not common, some people have
experienced withdrawal symptoms when stopping an
antidepressant too abruptly. Therefore, when discontinuing an
antidepressant, gradual withdrawal is generally
advisable.
Questions about any antidepressant prescribed,
or problems that may be related to the medication, should be
discussed with the doctor and/or the
pharmacist.
ANTIANXIETY
MEDICATIONS
Everyone
experiences anxiety at one time or another—"butterflies in the
stomach" before giving a speech or sweaty palms during a job
interview are common symptoms. Other symptoms include
irritability, uneasiness, jumpiness, feelings of apprehension,
rapid or irregular heartbeat, stomachache, nausea, faintness,
and breathing problems.
Anxiety is
often manageable and mild, but sometimes it can present
serious problems. A high level or prolonged state of anxiety
can make the activities of daily life difficult or impossible.
People may have generalized anxiety disorder (GAD) or more
specific anxiety disorders such as panic, phobias,
obsessive-compulsive disorder (OCD), or post-traumatic stress
disorder (PTSD).
Both
antidepressants and antianxiety medications are used to treat
anxiety disorders. The broad-spectrum activity of most
antidepressants provides effectiveness in anxiety disorders as
well as depression. The first medication specifically approved
for use in the treatment of OCD was the tricyclic
antidepressant clomipramine (Anafranil). The SSRIs,
fluoxetine (Prozac), fluvoxamine (Luvox),
paroxetine (Paxil), and sertraline (Zoloft) have
now been approved for use with OCD. Paroxetine has also been
approved for social anxiety disorder (social phobia), GAD, and
panic disorder; and sertraline is approved for panic disorder
and PTSD. Venlafaxine (Effexor) has been approved for
GAD.
Antianxiety
medications include the benzodiazepines, which can relieve
symptoms within a short time. They have relatively few side
effects: drowsiness and loss of coordination are most common;
fatigue and mental slowing or confusion can also occur. These
effects make it dangerous for people taking benzodiazepines to
drive or operate some machinery. Other side effects are
rare.
Benzodiazepines vary in duration of action in
different people; they may be taken two or three times a day,
sometimes only once a day, or just on an "as-needed" basis.
Dosage is generally started at a low level and gradually
raised until symptoms are diminished or removed. The dosage
will vary a great deal depending on the symptoms and the
individual's body chemistry.
It is wise
to abstain from alcohol when taking benzodiazepines, because
the interaction between benzodiazepines and alcohol can lead
to serious and possibly life-threatening complications. It is
also important to tell the doctor about other medications
being taken.
People
taking benzodiazepines for weeks or months may develop
tolerance for and dependence on these drugs. Abuse and
withdrawal reactions are also possible. For these reasons, the
medications are generally prescribed for brief periods of
time—days or weeks—and sometimes just for stressful situations
or anxiety attacks. However, some patients may need long-term
treatment.
It is
essential to talk with the doctor before discontinuing a
benzodiazepine. A withdrawal reaction may occur if the
treatment is stopped abruptly. Symptoms may include anxiety,
shakiness, headache, dizziness, sleeplessness, loss of
appetite, or in extreme cases, seizures. A withdrawal reaction
may be mistaken for a return of the anxiety because many of
the symptoms are similar. After a person has taken
benzodiazepines for an extended period, the dosage is
gradually reduced before it is stopped completely. Commonly
used benzodiazepines include clonazepam (Klonopin),
alprazolam (Xanax), diazepam (Valium), and
lorazepam (Ativan).
The only
medication specifically for anxiety disorders other than the
benzodiazepines is buspirone (BuSpar). Unlike the
benzodiazepines, buspirone must be taken consistently for at
least 2 weeks to achieve an antianxiety effect and therefore
cannot be used on an "as-needed" basis.
Beta
blockers, medications often used to treat heart conditions and
high blood pressure, are sometimes used to control
"performance anxiety" when the individual must face a specific
stressful situation—a speech, a presentation in class, or an
important meeting. Propranolol (Inderal, Inderide) is a
commonly used beta blocker.
MEDICATIONS FOR SPECIAL GROUPS
Children,
the elderly, and pregnant and nursing women have special
concerns and needs when taking psychotherapeutic medications.
Some effects of medications on the growing body, the aging
body, and the childbearing body are known, but much remains to
be learned. Research in these areas is
ongoing.
In general,
the information throughout this page applies to these
groups, but the following are a few special points to keep in
mind.
CHILDREN
The 1999
MECA Study (Methodology for Epidemiology of Mental Disorders
in Children and Adolescents) estimated that almost 21 percent
of U.S. children ages 9 to 17 had a diagnosable mental or
addictive disorder that caused at least some impairment. When
diagnostic criteria were limited to significant
functional impairment, the estimate dropped to 11 percent, for
a total of 4 million children who suffer from a psychiatric
disorder that limits their ability to
function.
It is easy
to overlook the seriousness of childhood mental disorders. In
children, these disorders may present symptoms that are
different from or less clear-cut than the same disorders in
adults. Younger children, especially, and sometimes older
children as well, may not talk about what is bothering them.
For this reason, it is important to have a doctor, another
mental health professional, or a psychiatric team examine the
child.
Many
treatments are available to help these children. The
treatments include both medications and
psychotherapy—behavioral therapy, treatment of impaired social
skills, parental and family therapy, and group therapy. The
therapy used is based on the child's diagnosis and individual
needs.
When the
decision is reached that a child should take medication,
active monitoring by all caretakers (parents, teachers, and
others who have charge of the child) is essential. Children
should be watched and questioned for side effects because many
children, especially younger ones, do not volunteer
information. They should also be monitored to see that they
are actually taking the medication and taking the proper
dosage on the correct schedule.
Childhood-onset depression and anxiety are
increasingly recognized and treated. However, the best-known
and most-treated childhood-onset mental disorder is attention
deficit hyperactivity disorder (ADHD). Children with ADHD
exhibit symptoms such as short attention span, excessive motor
activity, and impulsivity which interfere with their ability
to function especially at school. The medications most
commonly prescribed for ADHD are called stimulants. These
include methylphenidate (Ritalin, Metadate, Concerta),
amphetamine (Adderall), dextroamphetamine
(Dexedrine, Dextrostat), and pemoline (Cylert).
Because of its potential for serious side effects on the
liver, pemoline is not ordinarily used as a first-line therapy
for ADHD. Some antidepressants such as bupropion
(Wellbutrin) are often used as alternative medications
for ADHD for children who do not respond to or tolerate
stimulants.
Based on
clinical experience and medication knowledge, a physician may
prescribe to young children a medication that has been
approved by the FDA for use in adults or older children. This
use of the medication is called "off-label." Most medications
prescribed for childhood mental disorders, including many of
the newer medications that are proving helpful, are prescribed
off-label because only a few of them have been systematically
studied for safety and efficacy in children. Medications that
have not undergone such testing are dispensed with the
statement that "safety and efficacy have not been established
in pediatric patients." The FDA has been urging that products
be appropriately studied in children and has offered
incentives to drug manufacturers to carry out such testing.
The National Institutes of Health and the FDA are examining
the issue of medication research in children and are
developing new research approaches.
The use of
the other medications described in this booklet is more
limited with children than with adults. Therefore, a special
list of medications for children, with the ages approved for
their use, appears immediately after the general list of
medications. Also listed are NIMH publications with more
information on the treatment of both children and adults with
mental disorders.
THE
ELDERLY
Persons
over the age of 65 make up almost 13 percent of the population
of the United States, but they receive 30 percent of
prescriptions filled. The elderly generally have more medical
problems, and many of them are taking medications for more
than one of these conditions. In addition, they tend to be
more sensitive to medications. Even healthy older people
eliminate some medications from the body more slowly than
younger persons and therefore require a lower or less frequent
dosage to maintain an effective level of
medication.
The elderly
are also more likely to take too much of a medication
accidentally because they forget that they have taken a dose
and take another one. The use of a 7-day pill-box, as
described earlier in this brochure, can be especially helpful
for an elderly person.
The elderly
and those close to them—friends, relatives, caretakers—need to
pay special attention and watch for adverse (negative)
physical and psychological responses to medication. Because
they often take more medications—not only those prescribed but
also over-the-counter preparations and home, folk, or herbal
remedies—the possibility of adverse drug interactions is
high.
WOMEN DURING
THE CHILDBEARING YEARS
Because
there is a risk of birth defects with some psychotropic
medications during early pregnancy, a woman who is taking such
medication and wishes to become pregnant should discuss her
plans with her doctor. In general, it is desirable to minimize
or avoid the use of medication during early pregnancy. If a
woman on medication discovers that she is pregnant, she should
contact her doctor immediately. She and the doctor can decide
how best to handle her therapy during and following the
pregnancy. Some precautions that should be taken
are:
- If
possible, lithium should be discontinued during the first
trimester (first 3 months of pregnancy) because of an
increased risk of birth defects.
- If the
patient has been taking an anticonvulsant such as
carbamazepine (Tegretol) or valproic acid
(Depakote)—both of which have a somewhat higher risk
than lithium—an alternate treatment should be used if at all
possible. The risks of two other anticonvulsants,
lamotrigine (Lamictal) and gabapentin
(Neurontin) are unknown. An alternative medication
for any of the anticonvulsants might be a conventional
antipsychotic or an antidepressant, usually an SSRI. If
essential to the patient's health, an anticonvulsant should
be given at the lowest dose possible. It is especially
important when taking an anticonvulsant to take a
recommended dosage of folic acid during the first trimester.
- Benzodiazepines are not recommended during
the first trimester.
The
decision to use a psychotropic medication should be made only
after a careful discussion between the woman, her partner, and
her doctor about the risks and benefits to her and the baby.
If, after discussion, they agree it best to continue
medication, the lowest effective dosage should be used, or the
medication can be changed. For a woman with an anxiety
disorder, a change from a benzodiazepine to an antidepressant
might be considered. Cognitive-behavioral therapy may be
beneficial in helping an anxious or depressed person to lower
medication requirements. For women with severe mood disorders,
a course of electroconvulsive therapy (ECT) is sometimes
recommended during pregnancy as a means of minimizing exposure
to riskier treatments.
After the
baby is born, there are other considerations. Women with
bipolar disorder are at particularly high risk for a
postpartum episode. If they have stopped medication during
pregnancy, they may want to resume their medication just prior
to delivery or shortly thereafter. They will also need to be
especially careful to maintain their normal sleep-wake cycle.
Women who have histories of depression should be checked for
recurrent depression or postpartum depression during the
months after the birth of a child.
Women who
are planning to breastfeed should be aware that small amounts
of medication pass into the breast milk. In some cases, steps
can be taken to reduce the exposure of the nursing infant to
the mother's medication, for instance, by timing doses to
post-feeding sleep periods. The potential benefits and risks
of breastfeeding by a woman taking psychotropic medication
should be discussed and carefully weighed by the patient and
her physician.
A woman who
is taking birth control pills should be sure that her doctor
knows this. The estrogen in these pills may affect the
breakdown of medications by the body—for example, increasing
side effects of some antianxiety medications or reducing their
ability to relieve symptoms of anxiety. Also, some
medications, including carbamazepine and some antibiotics, and
an herbal supplement, St. John's wort, can cause an oral
contraceptive to be ineffective.
INDEX
OF MEDICATIONS
To find the
section of the text that describes a particular medication in
the lists below, find the generic (chemical) name and look it
up on the first list or find the trade (brand) name and look
it up on the second list. If the name of the medication does
not appear on the prescription label, ask the doctor or
pharmacist for it. (Note: Some drugs are marketed under
numerous trade names, not all of which can be listed in a
short publication like this one. If your medication's trade
name does not appear in the list—and some older medicines are
no longer listed by trade names—look it up by its generic name
or ask your doctor or pharmacist for more information.
